When Sam and Dean go hunting for the Alpha vampire with the Campbells, Dean sees them shoving the Alpha in a van instead of killing it. Since Sam was involved, Dean confronts him about it and realises Sam has got no intuition with his soul gone. Dean then tries to convince Sam that their grandfather might not be such a good guy and that they need to find out what he's hiding.
